HUMIDIFYING AIPPAIRA'IUS.

To all whom it may concern: A

e-it known that 1, WILLIAM J. KELLEY, of Central Falls, ,in the county of Providence, and State of Rhode Island, have invented certain new and useful Im rovements in Humidifying Apparatus, of W 'ch the following is a specification.

This invention relates to that class ofapparatus for moistening air, particularly in factories for treating textile materials, in which water and air under pressure 'are admitted simultaneously to a delivering conduit or nozzle, which is provided with means I for causing the water to be distributed in the form of fine spray or fog the delivering'conduit being provided with a deflector which is opposed to the delivering end, so that the air and water impin e upon the deflector, and are distributed in t e form and. the de ector.

of a fine spray or fog.

from the 1pipe 13, the ipe 12 being connected wit the said con uit by a branch 16, and'the pipe 13 by a branch 17'. The conduit 15 has an open" delivering end 18 surrounded by an annular face 19 (Fig. 4).

20 represents the deflector, Which has a face 21 opposed to the end face 19 and parallel therewith, the deflector being movable endwise toward and from the conduit 15, so that when thedeflector is in its operative position, shown in Fig. 4, the faces 19 and 21 will form the sid of a narrow annular crevice through w 'cii water flowing through the conduit 15, will be fcrced outwardly in a thin circular sheet of fines ray or fog by air under pressure supplied to t e said conduit. A

The conduit 15 is providedwith a cage, which is entirely external to the conduit, and

- is adapted to guide the deflector in its movements toward and from the open end ofthe conduit. Said cage,'as here-shown, includes a guide 22 and rods 23 23 rigidly connected to the ide and to the conduit, the guide being of elongated body of the deflector. The deflector body is movable in the guide toward and from the open end of the conduit,'and means are provided for securing" the deflector to the guide in any osition to which the deflector is capable 0 being adjusted,

said means, in this embodiment of my inventlon, including an external screw thread formed on the gu1de, and an internal screw ,thread 24formed in a portion of the deannular form, and surrounding the flector, and engaging the external thread on a the guide. The portion ofthe deflector on which the internal thread 245 is formed, is preferably a cup25' connected with the body of the deflector by a screw 26, and adapted 5 to be rotated to cause an endwise adjustment of the deflector.

When the apparatus is in operation, the deflector is brought into very close proximity to the open end of the conduit, as indicated in Fig. 4:,s0 that the opposed faces 19 and 21 form an annular outlet crevice, the conductingahapacity of which is much less than that of tlieopenend 18 of the conduit 15, so that thecompressed air sucpplied to the conduit,

will be eld back un er a considerable degree of compression within the conduit,.an l

will-therefore pass through the restricted crevice with such force as to convert all the water passing throughtheiconduit into fine spray or fog, and blow the same outwardly The said result is due to the fact that the open end of the delivering conduit 15 is en- .tirely unobstructed internally, the deflector. being supported Wholly by meansexternal to the de vering conduit, so that the entire interior of the conducting capacity of the conduit is utilized in bringln air under pressure to the crevice formed y the opposed faces 19 and 21. The importance of means external to the conduit for supporting and the deflector, will be appreciated of water from the deflector or thatwhen the ar when t e fact is borne in mind that dropping distributer of a humidifying apparatus,- even at comparatively infrequent intervals, is sufiicient to condemn the apparatus, and prevent its use in atextile factory. The quantity of water admitted to the/conduit 15 is relatively small, so that the communication between the water-admitting branch 16 and the conduit l5.must be suitably restricted, so that water enters the conduit dropby drop,

"of-in an extremely attenuated stream. The branch 16 is connected with the conduit'15 by an elbow-shaed casing 28 havingan arm 29 with which t e branch 16 is-connected, and an arm 30 with which the conduit 15 is connected, as shown in Fig. 6. The

casin 28 has a valve seat 31 surrounding the liqui entrance into the casing, and a valve 32 which ismovabletoward and from said seat, the valvehaving a screw-threaded stem 33 engaged with a nut 34: forming a part of the casing. ,The rotation of the stem in said nutscauses the valve to move toward and from they seat. The stem is provided with an operating lever having two arms 35 3"?) pro j eating in opposite directions from the stem, theouter en s of said arms being adaptedto engage depending cords or chains by which the two armed lever may be turned in either direction to move the valvetoward or from its seat. 37 represents an adjustable stop, which. is preferably. a screw working in a tapped socket in a fixed supp'ort -38, said stop being arranged to limit the'movement of the arm 35 in the direction indicated by the arrow an in Fig. 5, this being the direction of movement required to move the valve toward its scat: The stop 37 is, so adjusted "35 abuts against 1t, the

valve will be at the exact distance from the v seat required to permit the desired restricted flow of water into the conduit 1.5, In case thepassage'between the valve and its seat open end of t ee'mae and ample opening;

air chamber, the mouth of which is surround:

ed by the face 21. This chamber contains .an air cushion, which is. compressed by the compressed air within the conduit 15, and materially aids in the distribution of the Water in the form of s ray or fog.

I do not 'mit mysel? to the details of construction h re shown, as the same may be variously modified without departing from the s hit of my invention.
